Figure 6 Correlation heatmap. The numbers and colors within the squares indicate the correlation coefficients between variables, where warm colors (e.g., red) represent negative correlations and cool colors (e.g., blue) represent positive correlations. The deeper the color, the stronger the correlation. ^aP < 0.05; ^bP < 0.01; ^cP < 0.001. MVI: Microvascular invasion.
